Some would say this is the mini-game for the King Arthur Pendragon RPG. This is all about running your manor which is something of a side issue to what your character does gloriously in an Arthurian setting.
That said, it’s a lot of fun for the right type of gamer.

You can make improvements for profit and/or to get checks to certain traits (an apiary will make you busy and therefore let you check the energetic trait every Winter Phase), you can get a traveling troupe which gives you a check to your intrigue as you now have a spy network, you can put up your manor defenses, you can hire specialists, you can get mercenaries and quite a bit more.

There is also a section on how you treat your peasants. If you treat them poorly there is a passion they pick up which is hatred towards their lord. Love it.

If you’re building an improvement with the intent to make a profit then an apiary seems to be the popular first choice.
